Results of the optimal discriminative model in distinguishing GBM from MBTs in the training and the testing groups.

Model	Training group				Testing group
	AUC	Accuracy	Sensitivity	Specificity	AUC	Accuracy	Sensitivity	Specificity
Distance correlation + LDA	0.80	0.80	0.75	0.85	0.80	0.78	0.69	0.86
Distance correlation + LR	0.83	0.83	0.79	0.87	0.80	0.79	0.71	0.85

AUC, area under curve; LDA, linear discriminant analysis; LR, Logistic Regression.
